Mercedes-Benz GL has gone since 2006 without an update, and for the 2013 model year, Mercedes will finally be paying attention to their big three-row SUV.

While the diesel GL models will be largely carried over, M-B's new line of turbocharged V8s and direct-injection V6s will make an appearance in the new model. Other changes will be largely cosmetic, with a new front and rear fascia being the most obvious details, as well as revised front and rear lights with a smattering of LEDs too.
